Ukuqonda izisekelo zokusebenza kokushintsha

Emhlabeni wokuxhumana, ama-switch asebenza njengomgogodla, ohamba kahle we-data amaphakethe ezindaweni zawo okuhlosiwe. Ukuqonda izisekelo zokushintsha ukusebenza kubalulekile ekubambeni ubunzima bezakhiwo zenethiwekhi yanamuhla.

Empeleni, i-switch stapton isebenza njengedivaysi ye-multiport esebenza engxenyeni yesixhumanisi sedatha yemodeli ye-Osi. Ngokungafani nama-hubs, asakaza idatha ngokungakhethi kuwo wonke amadivaysi axhunyiwe, ukushintshwa kungahambisa idatha ngokusobala kudivayisi ethile lapho uya khona, ethuthukisa ukusebenza kahle kwenethiwekhi nokuphepha.

Ukusebenza kwe-switch kuncike kwizakhi ezimbalwa ezibalulekile nezinqubo:

Ukufundwa Kwekheli le-MAC:
I-switch igcina itafula lekheli le-mac elihlanganisa amakheli we-Mac namachweba ahambelana nawo afunda. Lapho uhlaka lwedatha lufika ethekwini lokushintsha, ukushintshwa kubheka ikheli le-MAC le-MAC futhi livuselela itafula laso ngokufanele. Le nqubo inika amandla ukushintshela ukwenza izinqumo ezinolwazi mayelana nokuya phambili kwamafreyimu alandelayo.
Phambili:
Lapho nje i-switch ifunde ikheli le-MAC ledivayisi exhunywe ethekwini layo, lingadlulisela amafreyimu kahle. Lapho uhlaka lufika, i-switch ishintsha itafula lekheli le-mac ukuthola imbobo efanelekile yekheli le-mac. Uhlaka ludluliselwa kuphela kulelo chwephetha, ukunciphisa ithrafikhi engenasidingo kunethiwekhi.
Ukusakazwa nokukhukhula okungaziwa kwe-UNICAST:
Uma i-switch ithola uhlaka olunekheli le-mac elikhona elingatholakali etafuleni lekheli le-mac, noma uma uhlaka lumiselwe ikheli lokusakaza, i-switchch isebenzisa izikhukhula. Kudlulisela amafreyimu kuwo wonke amachweba ngaphandle kwechweba lapho kutholwa khona uhlaka, ukuqinisekisa ukuthi uhlaka lufinyelela lapho uya khona.
Iphrothokholi yokusolwa kwekheli (i-ARP):
Ukushintsha kudlala indima ebalulekile ekuhlinzekeni inqubo yenqubo ye-arp ngaphakathi kwenethiwekhi. Lapho idivaysi idinga ukunquma ikheli le-MAC elihambelana nekheli elithile le-IP, isakaza isicelo se-ARP. Ukushintshela kudlulisela isicelo kuwo wonke amachweba ngaphandle kwechweba lapho isicelo samukelwa khona, sivumela insiza ngekheli le-IP eliceliwe ukuze uphendule ngqo.
Ama-Vlans neziqu:
Ama-Virtual Lans (VLANS) avumela ukushintshwa kokuhlukanisa inethiwekhi ibe izizinda ezahlukahlukene zokusakaza, ukwenza ngcono ukusebenza nokuphepha. I-Trunking inika amandla ukushintshela ukuthwala ithrafikhi kusuka kuma-Vlala amaningi ngaphezulu kwesixhumanisi esisodwa somzimba, ukuguquguquka okukhulayo ekuklameni kwenethiwekhi nokucushwa.
Ngamafuphi, ukushintshwa kwakha i-Cornerstone yengqalasizinda yanamuhla yenethiwekhi, lula ukuxhumana okusebenzayo nokuvikelekile phakathi kwamadivayisi. Ngokufaka phakathi kokusebenza kwe-switch of switchch, abaphathi benethiwekhi bangathuthukisa ukuphepha, bathuthukise ukuphepha, futhi baqinisekise ukuhamba komthungo kwemininingwane kuyo yonke inethiwekhi.

UTonda ubheka ukukhiqiza ukushintshanisa futhi wenza ngokwezifiso ukwakhiwa kwenethiwekhi kwamabhizinisi.
